Bet that old drill was built like a tank though. Probably outlasts the new stuff they sell now. @kevinw94 I've seen old timers bring stuff like that on purpose, they don't trust the new batteries to hold a charge all day.

Heard that @adam414, but do you really think a text would hold up if they just claim it was a typo?

That Sony A7III sample rate thing got me too with a Zoom H6 once.

Miller's video on that saved me too a couple years back. I was doing a bunch of repair work on a pressure vessel and kept getting these little pinholes. Drove me nuts for two days. Turned out I had a 50 foot hose and was running it at 20 CFH. Dropped it to 35 CFH and the problems vanished. What gets you is most people think more gas is better but with a long whip you actually starve the arc. The gas gets turbulent by the time it hits the puddle. I keep a little card in my lid with flow rates for different hose lengths now. Cheap fix for a headache that'll ruin your week.

Does anyone actually read those 10 page decks? Most clients just want to know if they can afford you and if you get the problem. Short proposals force you to be clear, that's probably why they work better.
